To understand why an "instant" solution is impossible, one must first confront the brute mathematics of pixels. Standard high-definition (1080p) contains just over 2 million pixels. 4K UHD contains over 8 million. To "instantly" convert 1080p to 4K, a plugin would need to invent 6 million new pixels out of thin air. Traditional upscaling—bicubic or Lanczos interpolation—is indeed instant, but it is not a "plugin" so much as a native, dumb algorithm. It simply guesses the color of new pixels by averaging the colors of their neighbors. The result is a larger image that is soft, plastic-looking, and devoid of true detail. Professionals refer to this as "empty resolution." It allows you to zoom in further, but it reveals no new information; it simply magnifies the old blur.
