I managed to grab one of the decently sized Prendergast gyutos a while ago. Iron clad W2, 252×53mm. It isn't quite a laser, but a fairly light middleweight with light convexity the in the rear 2/3, and nearly flat near the tip.
As the title alludes, I'm on the fence about polishing this blade. While I think it'd look nice with a nice kasumi, I suspect the fairly rough finish helps with food release. The bevels look pretty good: no glaring high/low spots, so I shouldn't be losing too much metal in the potential process.
What are your learned opinions?

If you like it just fine how it is right now and you’re enjoying using it, I’d say just crack on using it. Especially if you haven’t done a full kasumi before.

It will take a while to get a full polish on there, the integral bolster could get in the way, and it could end up being a while before it looks good.

This is heavily biased by my own experiences where a knife I otherwise really liked ended up sat on my projects bench for weeks.
 
+1 on avoiding integral bolsters for polishing projects. They are a pain to deal with. This looks like it would be quite the undertaking and one I would be hesitant to do myself. You could easily spend 20 - 40 hours on this thing and not be satisfied with the end result.
 
I agree that it'll very likely look excellent with a well done kasumi on it.

Just going by the pics you posted: to get an even polish on this knife is a really, really massive amount of work. Something like 85%+ of the entire surface area will end up needing to be polished. Those low grit belt marks are pretty deep, it's almost certain that they're hiding a good amount of topography once you start working them out. Add in having to do all this with a complex convex to flat grind and add in the integral bolster to work on/contend with and 40 hours is probably underestimating the total time for anyone who's reasonably proficient with this sort of thing. I'd bet that it would end up taking 2-3x that time estimate.
 
Find it hard to see how polishing would benefit to the blade's performance or its looks. You now have a pretty patina. A polish is likely to cause sticking, and certainly won't stay all that nice.
 
I had one in the past and when I wanted to thin/remove patina, I just hit it at the same angle with a scotch bright belt when I was done. With that bolster I would be more inclined to use sand paper progressions to get rid of the lines
