>>33779332>GIF color paletteThat's a great guess!
1. The distribution of numbers does seem to hint that this is RGB888
2. When converted into a 256-color palette, it creates a pretty soft set of colors that gradually grow brighter. Be it a bunch of random data, it would've probably looked like a high contrast mess
3. That color palette easily injects into that gradient gif at an offset of 13 bytes from the start. Pic is the result. The gradient gif has a color palette with exactly 256 entries, which turns out to be exactly 768 bytes long with 3 colors. The other couple of gifs I've checked had a shorter palette. The palette in the original gif also stands out because it's made entirely out of increasing numbers.
4. That palette kinda reminds me of cammyBut the background image from where the exif data came from was first spotted on 2018.10.21 and the gradient gif was first spotted on 2019.04.18. That's a substantial time gap, which, combined with the fact that the gif still doesn't seem to represent anything, makes me think that all of the above was just a strangely unusual coincidence, but I'm really not sure
