What are these areas with different colors in my video?

I'm new to photography, I bought my P4 a week ago, and while editing on Davinci Resolve 12.5 I've notice the following:

In this very zoomed in pic you can see that there are many of these spots that have a different color (more yellowish or reddish).

In the first image I used red lines so you can understand what I'm talking about. This is a Dlog -2 -3 -2 graded image with Auto white balance and shutter speed (not using ND), but with or without color grading they are still visible.

This is a screenshot of a video. As I play the video these marks appear in different places.

Is that normal? Is it just compression?
I think I can see them on .mp4 and .mov rendered files too. They are also visible if I don't use D-log.
Is it chromatic aberration or something like that? If you zoom out they are not really visible.

Just looks like H264 block compression to me... Tree foilage is a notorious for compression, as it's subtle differences in colour and texture make it difficult to estimate the frames
