Is the QN80F worth it over the QN90F?

The QN90F has a brighter panel and better local dimming. The QN80F costs less and still delivers a strong Neo QLED picture, so it is the better value unless you watch a lot of dark-room content.

No. Samsung supports HDR10 and HDR10+, not Dolby Vision. If Dolby Vision matters, look at LG or Sony sets.

The TV, a stand, a remote, a power cable and the manual. A wall mount is not included.
