Maybe I'll get around to installing Windows 10 on my new Mac with an AMD Polaris GPU. That should give some clues how the behavior developed since then.
I totally forgot that I had a desktop box with a Radeon RX 580 card (Polaris I think) and Windows 10 under my desk. Attached are results with your filtering settings and point filtering everywhere.
On a quick look it seems that it also has the 0.5 texel offset, but has some precision issues with the colors it writes. You may have to increase the allowed slop in the color comparisons. Maybe you can also add or subtract one from the expected results and keep everything happy with the current slop.
