So i just got my gopro black 7 and started testing.
I cant seem to get the same quality on youtube as gopro does on their own channel (or even other 4k travel gorpo videos)
for example :HERE (and again, im just talking quality)
4K @ 30fps @ wide
Protune on (flat, iso 100-400, shutter auto)
Using imovie, exporting in max quality (prores)
File ends up being ~ 55kbs bitrate
I know YouTube compresses the video again, but given the same workflow, i think i should be able to get the same quality (no content of course)
A couple possible theories:
Do channels pay youtube for increased bitrates?
Does Imovie use bad compression vs adobe premier pro or another more professional software?

It's hard to say because you didn't link to any of your footage. All you did was post a link to GoPro's footage.
There could be many reasons your footage doesn't look as good such as
A: Recoding in a flat profile but not color grading your material afterwards in the editing process.
B: Uninspiring subject
C: Encoding issues.
D: Uploading issues
E: Low bit rate on rendered footage
F: Shooting settings not matching the environmental conditions
If the problem is your video's looking like they have a low bitrate (blocking) on youtube, don't forget, it takes a couple of hours for 4K videos to show up, they will process and make available a low quality video first. You may also need to increase the bit rate on your video's when editing them in post to ensure you're getting maximum quality. Also switching to a constant bit rate as opposed to a variable bit rate may also help.

Thanks for the comments,
Im waiting on youtube to render my sample video in 4K (deleted my old one). Will link as soon as its ready because I agree, hard to chat about it without seeing a sample.
But even before youtube, playing with VLC on my computer, it doesnt look as good. I color graded the sample a bit too, but im just talking about the details, just not as sharp as im seeing in other places.
to your specific suggestions:
A: Recoding in a flat profile but not color grading your material afterwards in the editing process. - I am not a professional, but trying to focus on the sharpness vs other detail for this test
B: Uninspiring subject - very true, just a sample video, but still just trying to focus on the details / sharpness
C: Encoding issues. - Im starting to think imovie compression isnt as good (even on prores) as maybe some of the better programs out there (adobe pro), but not sure if thats what causing the difference
D: Uploading issues - It could be youtube for sure, but somehow others are able to get better looking vids
E: Low bit rate on rendered footage - the resulting file bitrate is around 55, which i think should be fine for 4k
F: Shooting settings not matching the environmental conditions - possible, will show you when the sample is ready.

GoPros own videos are heavy post processed and color gradet with Adobe Premiere. Anoyne not using a 500 USD NLE will not get pro results.
