Walshed-off image when converting byte[] image to tex2d/sprite

Hello
When a user uploads an image (png or jpg) on my game I convert it at runtime as per below to a sprite but it renders washed off, particularly noticeable for blacks and whites.

Original image:

Converted image:

I develop on URP but I've tested the pipeline and it's not the problem - I manually assigned the image as Sprite (2D and UI) in the inspector to the UI and it looks fine.

This is the code I use:

Code (CSharp):

1. private void FileWasOpenedEventHandler(byte[] data)
2.     {
3. string path = UnityEditor.EditorUtility.OpenFilePanelWithFilters(title,localImagePath,filters);
4. byte[] fileContent = File.ReadAllBytes(path);
5.  
6. //bytes to texture2D
7. Texture2D thisTex2d = GetTexture2D(data, name);//placeholder rawimage component
8.  
9. //create sprite to attach to image component
10. Sprite thisSprite = Sprite.Create(thisTex2D, new Rect(0.0f, 0.0f, RGBTexture2d.width, RGBTexture2d.height), Vector2.one);
11.  
12. Hero.GetComponent<Image>().sprite = thisPropSprite;
13. }
14.  
15. public Texture2D GetTexture2D(byte[] data, string name)
16.         {
17.             var texture = new Texture2D(2, 2, TextureFormat.ARGB32, false, true);
18.             texture.LoadImage(data);
19.             texture.Apply();
20.             return texture;
21.         }
22.  

Can someone please shed some light as to what I may be doing wrong or considerations?

Thanks a bunch

 

Please ignore, if it helps anyone TextureFormat was the culprit
var texture = new Texture2D(2, 2, TextureFormat.BGRA32, false);
