RSpec Expect Hash to include an Array of key value pairs

Still learning Rspec as a whole, so thanks for patience.

Return value is this:

{ supermodel: {
    'id': 1,
    'name': 'J',
    'model_attributes': [
        {attr1: 'T', attrA: 1}, 
        {attr2: 'F', attrB: 2}, 
        {attr3: 'T', attrC: 3}
        ],
    }
}

Trying to get an expectation that says that a hash key named 'model_attributes' contains a value of an array that includes the following key value pairs - {attr2:F, attrB: 2} and {attr3: T, attrC: 3}.

Any insight would be welcome.

describe 'Stuff' do
  let(:model_attributes) do
    [
      {attr1: 'T', attrA: 1}, 
      {attr2: 'F', attrB: 2}, 
      {attr3: 'T', attrC: 3}
    ]
  end
  let(:result) do
    { supermodel: 
      {
        'id': 1,
        'name': 'J',
        'model_attributes': model_attributes
      }
    }
  end

  it 'has the correct model_attributes value' do
    expect(result.dig(:supermodel, :model_attributes)).to eq(model_attributes)
  end
end
