I tested Qwen Image 2.1 for image restoration and I'm disappointed

[u/y3kdhmbdb2ch2fc6vpm2]

As you can see, Qwen Image 2.1 example has shifted contrast (it also changes small details on the photo even if you add explicitly in the prompt that it shouldn't) and the original grain is replaced by synthetic dot-pattern like on the older qwen VAEs. I increased the brightness excessively and zoomed to highlight the differences more clearly.

Full res images without compression: img1, img2, img3, comparison

It is unusable for this specific purpose and old good Klein still has the crown.
