Yes, changing the resolution will (expectedly) at least somehow change the color perception.
Note that your way of comparing the colors might be flawed.
Depending on the player and the used video renderer, opening multiple instances might produce different color handling.
You might want to check whether the displayed colors change, if you open the files in a different order.
Personally, I would
a. open the files in a Vapoursynth script (without the HDR data) for comparison. (assuming the hdr metadata are the same, one can ignore them for comparing)
b. not use Lanczos, but SSIM, DPID, ResampleHQ or Spline64 for down scaling. (not sure whether they all work fine on HDR content)
Not knowing what you really did in Hybrid, I doubt this is a bug.
