supportedPictureModes – only EyeComfort and Optimised
Hi. 
I've been struggling for a long time with setting Switcher to switch Picture Mode - Dynamic/Standard.

However, after several hours of unsuccessful attempts, I found that you can look at STATUS (https://api.smartthings.com/v1/devices/deviceID/status), where you can also see all possible **supportedPictureModes**.... 

And here are mine (only two):
```
"custom.picturemode": {
    "pictureMode": {
        "value": "EyeComfort",
        "timestamp": "2023-09-18T19:16:46.513Z"
    },
    "supportedPictureModes": {
        "value": [
            "EyeComfort",
            "Optimised"
        ],
        "timestamp": "2023-09-18T19:16:46.513Z"
    },
    "supportedPictureModesMap": {
        "value": [
            {
                "id": "modeGen_589826",
                "name": "EyeComfort"
            },
            {
                "id": "modeIntelligent",
                "name": "Optimised"
            }
        ],
        "timestamp": "2023-09-18T19:16:46.513Z"
    }
},
``` 

What's my point? It might be useful to someone. I don't know why I don't have any other Picture Mode available. I have turned Intelligent Mode on and off, but I have not been able to add a switcher dynamic/standard.

**Possible improvement: add "EyeComfort" and "Optimised" picture modes to documentation.** 

Thank you!
