IBP compression does not render predictive frames, it predicts a frame, then compares it with the actual frame and then only compresses the difference.
GH5 Evaluating GH5 4K 10bit clips recorded at both 150Mbps and 400Mbps.

Sorru. Difficult to make this post. I make it again.
A static frame may break also if the i-frames get too little bitrate. It is like a bad JPG compression. I think GH5 static frame is a little tiny bit better in 150Mbs ipb than 400Mbs all-i.
Here isan uncompressed png which show than GH5 all-i can have more errors than ipb. The frames are of course heavily adjusted.

In complex motion all-i is better. Here is high shutter speed motion frame enlargement ipb vs all-i
Seems that this site re-compresses my examples and makes the results smoother than originals
