Why only OLED use direct light emission, and on the other hand we only have LCD-based manipulation of backlight? Why can’t we have small LED blubs for each pixel of screen?

Answer 1

We do, called MicroLED (not to be confused with MiniLED).

The issue though is that for high resolution (and pixel density) there doesn’t exist LEDs small enough. So we are waiting for LED manufactures to meet demand. Currently the only MicroLED displays are large and lower resolution.
