That's a contradiction. If your Samsung player and your video card cannot play maxrate&bufsize >50000 they are not 4.1 compliant. High 4.1 is vbv maxrate 62500, bufsize 78125.
What usually happens is we use CRF encoding and barely reach high bitrates so we make wrong conclusions about level compliance of a device. You did the right thing by deliberately testing these high bitrates.
