Step Machine - is there any kind of intrinsic functions for if statements?

I'm pretty new to Step Machines, I've created a relatively complex machine - which works quite well and is hooked up to API gateway. There's one piece of it which just feels a bit ugly to me, I've created this example but let me be clear that this is a "fake" example so explaining better ways of doing it via the API or whatever doesn't help much, I just want to achieve what I'm showing below but ideally in a neater way. I should also add what I've done works, but just isn't pretty.

Basically I set a variable using the pass functions with two different outputs based on a choice, what it feels like I should be able to do is something LIKE;

"S.$": "States.If($.resolution>1000,'Desktop','Mobile')"

{
  "Comment": "A description of my state machine",
  "StartAt": "Choice",
  "States": {
    "Choice": {
      "Type": "Choice",
      "Choices": [
        {
          "Variable": "$.resolution",
          "NumericGreaterThan": 1000,
          "Next": "Status is OK"
        }
      ],
      "Default": "Status is Fail"
    },
    "Status is OK": {
      "Type": "Pass",
      "Next": "DynamoDB PutItem",
      "Result": {
        "type": "Desktop"
      },
      "ResultPath": "$.display"
    },
    "Status is Fail": {
      "Type": "Pass",
      "Next": "DynamoDB PutItem",
      "Result": {
        "type": "Mobile"
      },
      "ResultPath": "$.display"
    },
    "DynamoDB PutItem": {
      "Type": "Task",
      "Resource": "arn:aws:states:::dynamodb:putItem",
      "Parameters": {
        "TableName": "MyDynamoDBTable",
        "Item": {
          "Name": {
            "S.$": "$.name"
          },
          "DisplayType": {
            "S.$": "$.display.type"
          }
        }
      },
      "End": true
    }
  }
}
