In the provided repro project, there is an error on line 32 in "test2.cs" where "_MainTexture" should instead be "_MainTex", to match the property in the shader. With the error fixed, it looks like both cubes are indeed green and tex2D / UNITY_SAMPLE_TEX2DARRAY sample in the same way.

Reproduction steps:
1. Open the attached project “Shader Sampling Test”
2. Enter Play mode

Expected result: Both of the cubes are green
Actual result: One cube is green, the other cube is red

Reproducible with: 2020.3.40f1, 2021.3.12f1, 2022.1.20f1, 2022.2.0b11, 2023.1.0a14

Reproducible on: macOS 12.4 (Intel)
