Tested as fixed in 2.11-beta (and I believe in 2.10.2 too, but I'm not sure). See new attached images

Several commits in geotools and geoserver. I don't have time to look them up, but check the gs 2.10.2 and geotools 16.2 release notes for anything related to nodata and ROI. I believe they are at least 3 different tickets, maybe more.
