What are the known issues (link) and should I hold off on ISF calibration until the pulsating and cyan tint (?) issues are addressed?
Don't look for issues that you don't see. As I've said before, these forums have the potential to drive you crazy. If what you see is a great picture, then it's a great picture that you have.
To answer your question directly, there is a cyan color accuracy issue that's very difficult to see and only affects the color cyan and then only at lower luminance levels. Most never see it. In virtually all programming I watch, I simply don't see it (and I was the first to report on it, so I'm far from being in denial). Bottom line? Don't worry about it. I had my display ISF'd, so it didn't dissuade me. .
The other issue, pulsing, has already been partially addressed by Sharp via a software update. This has mitigated the pulsing issue to a large degree. Of course this assumes you had the issue to begin with. In my case I could see it in modes other than THX or ISF modes, but the issue disappeared in THX and ISF modes (even prior to the update). Those were the only two modes I used anyway. Again, if you don't see it you probably don't have it.
Sit back and enjoy the best picture out there.
