It's like some color lights seen as reflected by a little worn aluminium foil paper or cardboard. Here's at first an attempt to synthesize something resembling:
For a start paint some colors which together fill a layer totally:
Then apply a heavy Gaussian blur:
As you see the blurring reduces fully black, white and all original color areas, have them as large enough to compensate beforehand if the original color must be seen.
To distort it you need some displacement.A contrast boosted photo of foil paper could be used as a displacement map in Photoshop. I haven't such photo, so I inserted filter Ocean Ripple:
Try also Filter > Distort > Glass.
For more effect you can add an embossed photo of some scratches. I used this, it presented originally surface damages, but here it has got Photoshop's embossing filter:
With blending mode Hard light it gives this:
If you want something more realistic, get a real piece of metallized paper or cardboard, something like this:
Take a photo of a computer screen image which is reflected by the metal. Prepare some colorful image for the shot. Focus your camera to the metal. If you watch carefully your 2 last examples, you will see they use the same metallized surface.
As already said, you can also use metallized paper texture as a displacement map in Photoshops Distort > Displace -effect and you can extract some dimples and scratches with embossing from a surface image.
