Brightness adjustment

For the NFT preview, it would be necessary for you to light up your texture after baking it. to do this properly in Blender you would need to use the Compositing tab and activate "Use nodes"

Right after just drag and drop your baked NFT image into the Compositing work area and connect it to the Composite node from image output to image input

Now in the Add menu area, look for Color and pick the Hue Saturation Value node and connect it in between your image and the Composite node and set a Value of 3.5

Now add a Viewer node from the Add menu as shown in the next image

Connect the Hue Saturation Value Node to the viewer image input

Activate the image editor at any side of the Blender workspace

In the image editor look for Viewer Node preview in the image menu

Now from the image editor you can save you edited image from the image menu
