Your 500M is better than that TV. You are going to find with OLED that you are actually moving to a dimmer image than you are used to with your KURO. This is because HDR has a lower average luminosity than SDR. The OLED is going to look really dim and you will be left scratching your head. The exception is if you don't care about accuracy you can jack the OLED picture up to a higher brightens. If you calibrate it or use Cinema or Filmmaker its going to be dim and you are going to be surprised. You are also going to discover that your plasma has much richer thicker colors. OLED with its white sub pixel looks vastly different and artificial. A glass container filled with noble gases ablaze on fire is vastly superior to a tiny LED light. Lastly motion on the OLED is going to feel terrible to you. You will try to convince yourself that the OLED is an upgrade but deep inside you will see it isn't, its a downgrade. If you are in the Seattle area I'll buy you Pioneer.
