I would definitely love a display with better blacks! However, as long as LG (currently the only OLED supplier) doesn't get their image retention and burn-in in check, OLED is actually THE WORST option you can get for TDM and I am talking from experience.
About two years ago, I had bought one of LG's OLED TVs. At first, I was very excited about the contrast, color vibrance and sharpness (due to 4K), but soon the problems began to appear and the most critical one was: Image Retention! If you look at a high contrast scene with some bright spots for just a few seconds, e.g., when waiting for a guard to pass by, the bright pixels will burn-in. If you then walk into a rather dark room, you will still distinctly see residuals of the last scene, generating a clouding-like effect, and effectively destroying that suposedly superb contrast. Sure, if the scene is completely black, the pixels are switched off, generating that perfect black, but that's not how brightness is distributed on actual scenes. What good are perfect blacks if a display cannot show very dark-colors appropriately?
So, the best you can do right now is, to get an LCD with full-matrix LED backlight and local-dimming, which means the the backlight actually consists of multiple LEDs (basically like pixels) that can be switched on and off, which emulates that perfect black of the OLEDs quite well, albeit at a lower resolution, since you cannot switch those LEDs on a per-pixel level. Panasonic offered some great displays in this area, but the last time I looked (also two years ago), there were only 60Hz Panels, which is not enough for me because I am interested in 3DTV and they only offer Shutter-Technology for which you need high framerate.
By the way, I returned the OLED TV. There were just way too many issues with it. If you care to know, it wouldn't let me play 4K content via DLNA, which is my main source for content, and there was MASSIVE crosstalk when using its 3DTV capabilites. In order to visualize it, I displayed a black screen to the left eye and a white screen to the right eye. Now, have a look at what the left eye sees (should be 100% black).

That's crazy right?
