Kaio Ken has a cloaking device.
The coloured version is not a good argument. Besides this chapter not being originally in colour (which means that the painting job was not done by Toriyama) it even gives a KK aura to Freezer lol

There's nothing to learn. Goku's power surpassed Vegeta's without Kaio-Ken. That's a fact.
No, that's not a fact, because we later learned that Goku was already using the KKx10.

Reserve Power=Kaio-Ken x10
Look at the sequence of what takes place: Goku and Freeza up their powers. 50% Freeza easily dominated Kaio-Ken x10 Goku. Once this is clear, Piccolo says there was too much of a difference between their reserves. That means Goku indeed put forth more power during that part of the battle. That being the Kaio-Ken x10. Kaio never said Goku was using it the entire time. No one does.
Let's look at what is happening. Firstly, we are discussing if there was an invisible kaioh ken or if there wasn't. If according to you there wasn't any invisible Kaioh Ken, that means that Freezer increased his power to 50% only to hit Goku with a 10% of that power (5%).
Then Goku suddenly activated the KKx10, and Freezer, without even looking at him nor being able to feel kis, anticipated that and stomped him. Afterwards, Freezer proceeded to hit Goku with a 10% of his power again, for no apparent reason (to him), all while Kaito is saying that Goku is already using the KKx10 when he has no aura around him (in the page Kaito says Goku is using the KKx10, Goku has no aura).
That, or you are directly assuming that this is DBS and Goku enduring 50% Freezer's hits without any KK and then still being surpassed with the KKx10 makes any sense.
Regarding Piccolo's sentence, you have dozens of valid interpretations for it that wouldn't contradict the manga's internal rules. I mean, what if Goku was using the KKx10 the whole time but he had been reserving a bit of energy? (In other words, if let's say his power was 10 and became 100 with the KKx10, let's say he was fighting with a power of 9,5 which became 95 after the KKx10. Considering that increasing his Ki was much easier for him than increasing the level of KK, it would make more sense).
Or, considering that Ki sensing varied depending on the attitude of the fighter (Vegeta on the earth couldn't modulate his Ki at all, but he still surprised Goku when he adopted a more aggressive stance which means that in situations where the scoutter wouldn't vary his readings, the Ki sensing can in fact vary), what if Piccolo felt how Goku wasn't giving it all and he changed his attitude after Freezer used his 50% which could affect his perception on how much Ki was using Goku before and after doing that?
You have tons of explanations for what Piccolo says, and you choose to use the only one that breaks the manga's consistency in nearly every single way.
Freezer being suddenly able to anticipate a KKx10 activation without even looking at Goku and Goku resisting 50% Freezer's hits without the KKx10 when those hits were stronger than his KKx10 is plain bad writing and contradicts every other single fight seen in the manga.

Piccolo states Goku was hiding power here:
Chapter: 312 (DBZ 118), P13.2
Context: as Freeza beats up on Goku
Piccolo: “Th-this is bad…There’s too much of a gap between the power they were hiding…”
"The power they were hiding"... considering Goku was using Kaioken x10 at that moment, that was the power he was hiding. Therefore, he wasn't using Kaioken x10 before.
As I've said, you can explain this in a lot of ways that don't contradict the manga. Sadly, Goku activating the KKx10 for just a couple of panels after Freezer used his 50% is not one of them.
