Nice! Yeah, the optimal would be having a pass over the upscaled one, but pretty cool nonetheless!
If you are limited by VRAM, there are tiled upscale custom nodes, but I only use them for gens I really like - since they take a long time on large images.
Just in case you might need them in the future, I can suggest either UltimateSDUpscale, or the Efficiency Nodes has a sampler that takes a script as an input, pic related. The latter can use a ControlNet not to stray too far from the original image also. The input latent in that case is just the image VAE Encoded.

These are pretty hot
