Although the Pro dome is much much better than original the x5 footage still isn't good for anything else than vertical socials IMO. There are stitching artifacts usually where it matters :-) and the quality in low light is still poor and mushy. Apart from stitching artifacts - dome reflections - for the documentation I would say yes but then it gets quite big that PRO dome and so It gets in the way... So I would stick to action cam as a B-roll or fun dive camera.

and here is a screen grab converted to jpeg, the HDR version looks better.

I find that the procase is usable for more than just Social, although it is hard to judge when it will have an artifact from the case or will be usable. In particular, in the shallows there seems to be some reflection/refraction that it can't always deal with. So after the fact, it can produce some nice footage.

Here is a clip showing what it looks like in a darker situation (exported to 4k in non-360) - https://youtu.be/SPpYkaQvh1Y

Not amazing but sooooo much better than with the regular case. That was with Pure mode on and for context - to similarly expose the ice with a still shot @ F/10 and 1/50th - I was shooting ISO 8000. So dark.
