high number of reads in SQL Profiler but not when enabling Statistics - sql-server

Question

I am trying to troubleshoot a procedure that has a high number of reads in SQL Profiler, but not when I enable Statistics. It is a procedure that uses paging, and I am seeing about 17k reads on page 400 for instance, and the interesting part is that sometimes when I recompile the procedure that number drops to 1000-2000 as you can see in the screenshot. Lower pages show 1000 reads, with the number increasing as I move up:
Using SET STATISTICS IO ON in SSMS shows approximately 1000 reads even when Profiler says there are 17k:
And here is part of the procedure (the #users temp table has 4000 records in it):
SELECT [temp].[UserID] ,
[temp].[UserName] ,
[temp].[FirstName] ,
[temp].[LastName] ,
[temp].[CommissionRate] ,

) [temp]
CROSS APPLY [dbo].[fnContactDetailAggregateGetByContactID]([temp].[UserID]) [aggregate]
LEFT JOIN [dbo].[ContactAddress] [address] ON [address].[ContactID] = [temp].[UserID]
Here is the function:
CREATE FUNCTION [dbo].[fnContactDetailAggregateGetByContactID]
(
#ContactID INT
)
RETURNS #contact TABLE
(
[ContactID] INT PRIMARY KEY NOT NULL ,
[TelephoneCount] INT NULL ,
[Telephone] VARCHAR(255) NULL ,

[EmailAddress] VARCHAR(255) NULL
)
WITH SCHEMABINDING
AS
BEGIN
INSERT #contact
SELECT #ContactID ,
SUM(CASE WHEN [temp].[ContactDetailTypeID] = 1 THEN 1
ELSE 0
END) [TelephoneCount] ,
MAX(CASE WHEN [temp].[ContactDetailTypeID] = 1
THEN [temp].[ContactDetailValue]
END) [Telephone] ,
SUM(CASE WHEN [temp].[ContactDetailTypeID] = 3 THEN 1
ELSE 0
END) [EmailAddressCount] ,
MAX(CASE WHEN [temp].[ContactDetailTypeID] = 3
THEN [temp].[ContactDetailValue]
END) [EmailAddress]
FROM ( SELECT [detail].[ContactID] ,
[label].[ContactDetailTypeID] ,
FIRST_VALUE([detail].[ContactDetailValue]) OVER ( PARTITION BY [label].[ContactDetailTypeID] ORDER BY [detail].[Default] DESC ) [ContactDetailValue]
FROM [dbo].[ContactDetail] [detail]
INNER JOIN [dbo].[ContactDetailLabel] [label] ON [label].[ContactDetailLabelID] = [detail].[ContactDetailLabelID]
WHERE [detail].[ContactID] = #ContactID
) [temp]
RETURN
END
Any ideas what could be causing this and how I can go about fixing it?
