In WebGPU you can create a texture and request compatible viewFormats.

const tex = device.createTexture({
  ...
  format: 'rgba8unorm',
  viewFormats: ['rgba8unorm', 'rgba8norm-srgb'],
});

OpenGL ES 3.1 has no such facility.

We'd like to validate this out in compatibility mode. 2 options

1. Require the formats in viewFormats to be the same format

   { ... format: 'rgba8unorm', viewFormats: ['rgba8unorm', 'rgba8norm-srgb'], }  // bad
   { ... format: 'rgba8unorm', viewFormats: ['rgba8unorm'], }                    // ok

2. Require viewFormats to be unset

   { ... format: 'rgba8unorm', viewFormats: ['rgba8unorm'], }                    // bad
   { ... format: 'rgba8unorm' }                                                  // ok
