When calibrating any HDR display you MUST set it to a standard Power Law gamma, and then profile it.
You can then calibrate to any EOTF you want.
You cannot profile an HDR display with an EOTF active (especially one with roll-off/tine mapping) and then use that profile to calibrate it.
So, all the above graphs for both displays are with a standard Power law gamma, with Peak Luma set to HDR levels (700 to 800 nits in this case).
As there is no PQ EOTF active the displays should profile to themselves near perfectly, just as for the SDR tests that started this thread.
That is why the WOLED display data is so appalling - there is no PQ EOTF active, so the results should be near perfect.
