Reproduction steps:
1. Open the attached project "ShaderGraph.zip"
2. In the Project window open "b123.unity" Scene
3. Switch to Android and in the Player Settings set the Graphics API to OpenGL ES 2.0
3. Build for Android

Expected result: Pink textures are not displayed when using Graphics API Open GL 2.0 with Sample Texture 2D LOD Node
Actual result: Pink textures are displayed when using Graphics API Open GL 2.0 with Sample Texture 2D LOD Node

Reproduces on: Shader Graph 7.3.1 (2019.3.13f1), Shader Graph 8.1.0, 9.0.0 - preview.14 (2020.1.0b8, 2020.2.0a10)
Could not test on 2018.4 due to "sg-01" Shader Graph Shader missing several nodes

Reproduces with these devices:
N/A, Samsung Galaxy S9 (SM-G960F), Android 8.0.0, CPU: Exynos 9 Series 9810, GPU: Mali-G72
VLNQA00313, Huawei Y6 Ⅱ Compact (HUAWEI LYO-L01), Android 5.1, CPU: MediaTek MT6735, GPU: Mali-T720
VLNQA00140, Samsung Galaxy S4 (GT-I9505), Android 5.0.1, CPU: Snapdragon S4 Plus MSM8960, GPU: Adreno (TM) 320

Notes:
-The inability to use such node makes it impossible to manipulate vertices of the texture, as Sample Texture 2D (without LOD) can not be used for vertex-stage sampling. Thus the user needs to use the 'LOD' version of the node, but that one does not work on devices targeting GLES 2.0 API
-Does not reproduce with Vulkan and OpenGL ES 3.0
-When disconnecting the Sample Texture 2D LOD Node in "sg-01" Shader Graph Shader the texture is rendered properly
