LG is currently the only manufacturer that sells OLED sets in the U.S. and they only come in 55" and 65" sizes so no, it's not just you. I sure hope OLED becomes the next big tech because it looks amazing. With LG investing over 8 billion dollars in OLED and Panasonic partnering with them the future of the tech is looking brighter. I would think it won't be too much longer before OLED is more common and available in more sizes.
As for your kitchen TV, even if OLED was available in that small size it would likely be pricey. You're better off at this point with a small inexpensive LCD.
